-Represents a collection of a set of key and value pairs. Each key in the HashMap -must be unique, the same key cannot exist twice. Access to items is provided via -the key only. Sample usage: -
var map = new Ext.util.HashMap();
-map.add('key1', 1);
-map.add('key2', 2);
-map.add('key3', 3);
-
-map.each(function(key, value, length){
- console.log(key, value, length);
-});
-The HashMap is an unordered class, -there is no guarantee when iterating over the items that they will be in any particular -order. If this is required, then use a Ext.util.MixedCollection. -
- -A function that is used to retrieve a default key for a passed object. -A default is provided that returns the id property on the object. This function is only used -if the add method is called with a single argument.
-Adds an item to the collection. Fires the add event when complete.
-Adds an item to the collection. Fires the add event when complete.
-The key to associate with the item, or the new item.
- - -If a getKey implementation was specified for this HashMap, -or if the key of the stored items is in a property called id, -the HashMap will be able to derive the key for the new item. -In this case just pass the new item in this parameter.
- -The item to add.
-The item added.
-Removes all items from the hash.
-Removes all items from the hash.
-this
-Performs a shallow copy on this hash.

-The value to check for.
-True if the value exists in the dictionary.
-Checks whether a key exists in the hash.

-The key to check for.
-True if they key exists in the hash.
-Executes the specified function once for each item in the hash. -Returning false from the function will cease iteration.
- -The paramaters passed to the function are:
- -The key of the item
The value of the item
The total number of items in the hash
The function to execute.
-The scope to execute in. Defaults to this.
